IMPROVEMENT IN STOP-HINGES.

Specification forming part of Letters Patent No.145,3 l5, dated December 9, 1873; application filed April 30, 1673.

To all whom it may concern:

ABe it known that I, GEO. C. THOMAS, of Brooklyn, county of Kings, State of New York, have invented a Stop-Hinge, of which the following is a specification:

The object of the invention is to produce a hinge that will open a certain distance only, technically called a stop-hinge.77 Myinvention consists in forming the shoulder or stop with one of its sides coincident with the part of the blank which forms the eye ofthe hinge.

Figure l represents the ilat metal blank. Fig. 2 represents the joint of the hinge when closed. Fig. 3 represents the hinge open, back view. Fig. 4 represents the hinge open, inside View. Fig. 5 represents section through x, Fig. 2, and also sections through y y, Figs. 3 and 4.

e A A are the shoulders or stops, which, when the hinge is closed, as at Fig. 2, are some distance apart, but as it is opened they approach each other until they come in contact, as at Figs. 3 and 4, preventing its opening Wider,

and holding the lid of a box or other article to which it may be attached upright or at an angle, and not allowing it to open all the Way back. The shoulders or stops AA are solid lform is Weak, being supported on neither side.

This I do not clann; but

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A hinge the blanks or halves of which are formed with a shoulder or stop, A, having its side coincident with the part B, which forms the eye, all substantially as described and shown, for the purpose specified.

GEORGE C. THOMAS.
